Answer:
The answer to your question is 2.56 moles of NaCl
Explanation:
Data
moles of NaCl = ?
mass of Na = 59 g
mass of Cl₂ = excess
Process
1.- Write the balanced chemical reaction
2Na + Cl₂ ⇒ 2NaCl
2.- Calculate the atomic mass of Na
Na = 23 g
3.- Convert the mass of Na to moles
23 g of Na ---------------- 1 mol
59 g of Na ---------------- x
x = (59 x 1)/23
x = 2.56 moles
4.- Calculate the moles of NaCl using the coefficient s of the balanced equation.
2 moles of Na ---------------- 2 moles of NaCl
2.56 moles of Na ----------- x
x = (2.56 x 2) / 2
x = 2.56 moles of NaCl
